Mouse nutrition

What three-syllable word best describes a mouse's appetite? VORACIOUS! With their extremely high metabolisms, mice need to eat a lot to stay in tip-top condition. Alas, they're not too discriminating when it comes to grub – but that's where you come in. Once you know what, and what not, to feed your animal companions, you'll easily meet their nutritional needs.

What do mice eat?

Commercial rodent chow (in block or pellet form) should make up the bulk of your pets' diet. Nutritionally complete, this food is available at pet supply shops and feed stores. Try to find a formula that doesn't include seeds or nuts, which are too high in fats and oil, but does contain at least 16% protein and 18% fiber. No more than 4% of the formula should be fat.

Your pets should be able to feed freely on this food, so be sure it is available at all times. A sturdy ceramic food dish will work well, but many mouse caretakers sing the praises of specially designed wire dispensers that attach to the side of the cage. These dispensers allow mice to eat as they please, cut down on waste and minimize the chances of the food becoming contaminated by feces.

Hay and grains helps digestion

To keep your pets' digestive systems up and running, fresh grass hay or hay blocks should be available 24/7. You should also offer your furry friends small amounts of grains every day. Especially nice for mice are millet, barley and oats, and a nibble or two of whole grain bread. You may want to stay away from wheat, which has been known to cause trouble for some individuals.

Supplement a mouse diet with fruits and vegetables

Supplement your pets' diet with fresh fruits and vegetables every day. You may have to experiment to find their favorites, but peas, broccoli, carrots, apples and bananas are good foods to start with. Be sure to wash everything first, and never give your animals anything that's old or spoiled. And don't overdo it, please! Your pets have tiny tummies, after all, and too many fruits and veggies can cause diarrhea.

Topping the absolute no-no list are chocolate, corn and wheat. We know that many mouse parents give their pets sunflower seeds, but take it easy on them, please! These seeds are high in fat, and too many can lead to obesity. Also, take care to avoid peanuts, which are thought to cause skin rashes in some mice.

Don't forget that fresh, cool water should be available at all times. Get your pets set with a water bottle that attaches to the side of the cage. Rinse and refill it daily, and check that it does not become clogged.
